Overview
•
Integrated interface
•
Where to connect: Terminal strip inside the inverter
•
3-pin wiring

Communication address does not have to be assigned
Note:
The order in which the inverters are displayed in the Solar-Log™ after detection is random.
We strongly recommend that you change the order of the inverters immediately after de-
tection at startup in the

The wiring is done using a
•
self-made cable connection with terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector RJ45 inverter
